In a commissioning-authority-managed approach, who develops the commissioning plan and test procedures, and directs testing?

• A. The contractor
• B. The CxA
• C. The owner
• D. The facilities manager

Answer: (B)

In a commissioning-authority-managed approach, the Commissioning Authority takes the lead on planning and testing to ensure independent verification of performance. The commissioning plan is created to define scope, objectives, systems included, responsibilities, schedule, deliverables, and acceptance criteria. Along with that, test procedures are written to specify how each system will be tested, what data to collect, the sequence of tests, and the pass/fail criteria. The CxA then directs the testing process, coordinating with design and construction teams, reviewing results, issuing nonconformities as needed, and arranging retests until performance aligns with the design intent and owner requirements. This structure emphasizes objective validation rather than relying on the contractor or building staff to both plan and direct testing.
